自流井构造西段浅层天然气挖潜探讨

Discussion on Tapping the Potential Shallowly-Bedded Natural Gas in the Western Section of the Ziliujing Structure

自流井构造西段嘉陵江组四段一层至三段气藏开发40余年,文章重点对该气藏成矿地质条件、天然气储盖组合特征、有利构造部位、气水控制因素进行分析,提出天燃气挖潜有利构造位置。

The extraction of gas reservior from first layer of the fourth section to the third section of Jianglingjiang group of the western section of the Ziliujing Formation has been conducted for over 40 years. This paper lays stress on analyzing the geological conditions for metallogeny, the combined characters of the cover of natural gas reservoir, favorable tectonic lever and the gas-water control factors of this gas reservoir, and it also puts forward the favorable structural location for tapping the potential natural gas.
